title: 2-Bromo-5-fluoro-benzaldehyde.
abstract: In the title compound, C7H4BrFO, the benzaldehyde O atom is found to be trans to the 2-bromo substituent. In the crystal, short Br⋯F inter-actions between the bromine and fluorine substituents are observed at distances of 3.1878 (14), 3.3641 (13) and 3.3675 (14) Å. Offset face-to-face π-stacking inter-actions are also observed for both of the independent mol-ecules in the asymmetric unit running parallel to the crystallographic b axis, characterized by centroid-centroid distances of 3.8699 (2) and 3.8699 (2) Å.
